CVE-2016-8624 1 Haxx 1 Curl 2024-02-28 5.0 MEDIUM 7.5 HIGH
curl before version 7.51.0 doesn't parse the authority component of the URL correctly when the host name part ends with a '#' character, and could instead be tricked into connecting to a different host. This may have security implications if you for example use an URL parser that follows the RFC to check for allowed domains before using curl to request them.
CVE-2016-8623 1 Haxx 1 Curl 2024-02-28 5.0 MEDIUM 7.5 HIGH
A flaw was found in curl before version 7.51.0. The way curl handles cookies permits other threads to trigger a use-after-free leading to information disclosure.
CVE-2003-1605 1 Haxx 1 Curl 2024-02-28 5.0 MEDIUM 7.5 HIGH
curl 7.x before 7.10.7 sends CONNECT proxy credentials to the remote server.
CVE-2016-8621 1 Haxx 1 Curl 2024-02-28 5.0 MEDIUM 7.5 HIGH
The `curl_getdate` function in curl before version 7.51.0 is vulnerable to an out of bounds read if it receives an input with one digit short.
CVE-2018-14618 4 Canonical, Debian, Haxx and 1 more 4 Ubuntu Linux, Debian Linux, Libcurl and 1 more 2024-02-28 10.0 HIGH 9.8 CRITICAL
curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to allocate from the heap. The length value is then subsequently used to iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow. (This bug is almost identical to CVE-2017-8816.)
CVE-2016-8622 1 Haxx 1 Libcurl 2024-02-28 7.5 HIGH 9.8 CRITICAL
The URL percent-encoding decode function in libcurl before 7.51.0 is called `curl_easy_unescape`. Internally, even if this function would be made to allocate a unscape destination buffer larger than 2GB, it would return that new length in a signed 32 bit integer variable, thus the length would get either just truncated or both truncated and turned negative. That could then lead to libcurl writing outside of its heap based buffer.
CVE-2016-8619 1 Haxx 1 Curl 2024-02-28 7.5 HIGH 9.8 CRITICAL
The function `read_data()` in security.c in curl before version 7.51.0 is vulnerable to memory double free.
CVE-2019-3822 7 Canonical, Debian, Haxx and 4 more 16 Ubuntu Linux, Debian Linux, Libcurl and 13 more 2024-02-28 7.5 HIGH 9.8 CRITICAL
libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large 'nt response' data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a 'large value' needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.
CVE-2016-8616 1 Haxx 1 Curl 2024-02-28 4.3 MEDIUM 5.9 MEDIUM
A flaw was found in curl before version 7.51.0 When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that has connection-scoped credentials, an attacker can cause that connection to be reused if s/he knows the case-insensitive version of the correct password.
CVE-2016-8620 1 Haxx 1 Curl 2024-02-28 7.5 HIGH 9.8 CRITICAL
The 'globbing' feature in curl before version 7.51.0 has a flaw that leads to integer overflow and out-of-bounds read via user controlled input.
CVE-2019-3823 5 Canonical, Debian, Haxx and 2 more 7 Ubuntu Linux, Debian Linux, Libcurl and 4 more 2024-02-28 5.0 MEDIUM 7.5 HIGH
libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains no character ending the parsed number, and `len` is set to 5, then the `strtol()` call reads beyond the allocated buffer. The read contents will not be returned to the caller.
CVE-2017-2629 1 Haxx 1 Curl 2024-02-28 4.0 MEDIUM 6.5 MEDIUM
curl before 7.53.0 has an incorrect TLS Certificate Status Request extension feature that asks for a fresh proof of the server's certificate's validity in the code that checks for a test success or failure. It ends up always thinking there's valid proof, even when there is none or if the server doesn't support the TLS extension in question. This could lead to users not detecting when a server's certificate goes invalid or otherwise be mislead that the server is in a better shape than it is in reality. This flaw also exists in the command line tool (--cert-status).
CVE-2018-16890 8 Canonical, Debian, F5 and 5 more 10 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 7 more 2024-02-28 5.0 MEDIUM 7.5 HIGH
libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.
CVE-2016-8625 1 Haxx 1 Curl 2024-02-28 5.0 MEDIUM 7.5 HIGH
curl before version 7.51.0 uses outdated IDNA 2003 standard to handle International Domain Names and this may lead users to potentially and unknowingly issue network transfer requests to the wrong host.
CVE-2018-1000301 5 Canonical, Debian, Haxx and 2 more 9 Ubuntu Linux, Debian Linux, Curl and 6 more 2024-02-28 6.4 MEDIUM 9.1 CRITICAL
curl version curl 7.20.0 to and including curl 7.59.0 contains a CWE-126: Buffer Over-read vulnerability in denial of service that can result in curl can be tricked into reading data beyond the end of a heap based buffer used to store downloaded RTSP content.. This vulnerability appears to have been fixed in curl < 7.20.0 and curl >= 7.60.0.
CVE-2018-1000300 2 Canonical, Haxx 2 Ubuntu Linux, Curl 2024-02-28 7.5 HIGH 9.8 CRITICAL
curl version curl 7.54.1 to and including curl 7.59.0 contains a CWE-122: Heap-based Buffer Overflow vulnerability in denial of service and more that can result in curl might overflow a heap based memory buffer when closing down an FTP connection with very long server command replies.. This vulnerability appears to have been fixed in curl < 7.54.1 and curl >= 7.60.0.
CVE-2016-9586 1 Haxx 1 Curl 2024-02-28 6.8 MEDIUM 8.1 HIGH
curl before version 7.52.0 is vulnerable to a buffer overflow when doing a large floating point output in libcurl's implementation of the printf() functions. If there are any application that accepts a format string from the outside without necessary input filtering, it could allow remote attacks.
CVE-2018-1000007 5 Canonical, Debian, Fujitsu and 2 more 20 Ubuntu Linux, Debian Linux, M10-1 and 17 more 2024-02-28 5.0 MEDIUM 9.8 CRITICAL
libcurl 7.1 through 7.57.0 might accidentally leak authentication data to third parties. When asked to send custom headers in its HTTP requests, libcurl will send that set of headers first to the host in the initial URL but also, if asked to follow redirects and a 30X HTTP response code is returned, to the host mentioned in URL in the `Location:` response header value. Sending the same set of headers to subsequent hosts is in particular a problem for applications that pass on custom `Authorization:` headers, as this header often contains privacy sensitive information or data that could allow others to impersonate the libcurl-using client's request.
CVE-2017-2628 2 Haxx, Redhat 4 Curl, Enterprise Linux Desktop, Enterprise Linux Server and 1 more 2024-02-28 7.5 HIGH 9.8 CRITICAL
curl, as shipped in Red Hat Enterprise Linux 6 before version 7.19.7-53, did not correctly backport the fix for CVE-2015-3148 because it did not reflect the fact that the HAVE_GSSAPI define was meanwhile substituted by USE_HTTP_NEGOTIATE. This issue was introduced in RHEL 6.7 and affects RHEL 6 curl only.
CVE-2016-9594 1 Haxx 1 Curl 2024-02-28 6.8 MEDIUM 8.1 HIGH
curl before version 7.52.1 is vulnerable to an uninitialized random in libcurl's internal function that returns a good 32bit random value. Having a weak or virtually non-existent random value makes the operations that use it vulnerable.
